DESCRIPTION

: DHT22 output calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.Its sensing elements is connected with 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in type of programme in OTP memory, when the sensor is detecting, it will cite coefficient from memory. Small size & low consumption & long transmission distance(20m) enable DHT22 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient. 3. Technical Specification: Model Power supply Output signal Sensing element Operating range Accuracy Resolution or sensitivity Repeatability Humidity hysteresis Long-term Stability Sensing period Interchangeability Dimensions DHT22 3.3-6V DC digital signal via single-bus Polymer capacitor humi...
